Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install remark-lint-no-literal-urls

In Deno with esm.sh:

import remarkLintNoLiteralUrls from 'https://esm.sh/remark-lint-no-literal-urls@3'

In browsers with esm.sh:

<script type="module">
  import remarkLintNoLiteralUrls from 'https://esm.sh/remark-lint-no-literal-urls@3?bundle'
</script>

Use

On the API:

import remarkLint from 'remark-lint'
import remarkLintNoLiteralUrls from 'remark-lint-no-literal-urls'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

const file = await read('example.md')

await unified()
  .use(remarkParse)
  .use(remarkLint)
  .use(remarkLintNoLiteralUrls)
  .use(remarkStringify)
  .process(file)

console.error(reporter(file))

On the CLI:

remark --frail --use remark-lint --use remark-lint-no-literal-urls .

On the CLI in a config file (here a package.json):

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-no-literal-urls",
     …
   ]
 }
 …

API

This package exports no identifiers. It exports no additional TypeScript types. The default export is remarkLintNoLiteralUrls.

unified().use(remarkLintNoLiteralUrls)

Warn when GFM autolink literals are used.

Parameters

There are no options.

Returns

Transform (Transformer from unified).

Recommendation

GFM autolink literals (just a raw URL) are a feature enabled by GFM. They don’t work everywhere. So, it’s recommended to instead use regular autolinks (<https://url>) or full links ([text](url)).

Fix

remark-stringify never generates GFM autolink literals. It always generates regular autolinks or full links.

Examples

ok.md

In

<http://foo.bar/baz>

Out

No messages.

not-ok.md

In

👉 Note: this example uses GFM (remark-gfm).

http://foo.bar/baz

Out

1:1-1:19: Don’t use literal URLs without angle brackets

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-lint-no-literal-urls@3, compatible with Node.js 12.
